Appttcntton med Beptenabcr 16. 1908. Scrtal No. 463.340.

To all wlmm it may concern:

Be it known that I, lrz'ri-m Scuum, a citizen of the U uitcd States. residing at ('lc\'cland, in the county of (uyahoga and State of Ohio, have invented a certain new and useful Improveuwut. in lleaters, of which the following is a full, clear and exact description, reference being had to the accompanying drawings.

My invention relates to heaters, more particularly to gas heaters, and provides a heatinc devlce in which the products of coluhustion from the burner are. caused to travel in a sinuous course while the air to he heated is brought into intimate contact with the conduits which carrv the air. .\lorco\'cr, hy the construction which I have provided, a column of fresh, cool air ascends through a central duct of the heater, which cool air issurrounded by the flue mcmher that carries the products of combustion from the burner. Likewise, asccond, hollow column of fresh, cool air Mcenda through the heater upon the outside of the flue me'nher. 'l'lnui the flue member is enveloped, as it were, with the cool alr upon all aides, which results th'at practically all the heat in the products of combustion is extlactcd therefrom and ahsorhed by the air passing thlou 'h the heat ing device, which air is to he de ivered to the room or rooms to he heated.

Generally npcaking, the invention comprises the elementu amt eomhinat ions thereof set forth in the acconnmuyiug, claims.

Reference should he had to the accompanying drawings forming a part of this specification, in which- Figure I is a central vertical section through the heater and inclosing casing; Fig. 2 is a top plan viewof the heating device: Fig. 3 is a section taken upon the line 3 -3 of Fi 1; and Fig. 4 is a vertical section upon the hue 4-4 of Fig. 2 taken in the direction of the tlllowtt.

Generally speaking, the invention comprises a homer, and heating device through which air is caused to pass and ahxorh heat from the. n'oducta of comhustion from the burner. he said de\'ice and hurncr are surrounded hy a casing which is in communication with suitahle pipes for conducting the heated air to the duct! or places that mar he deaired. Upont ie hose 1 is mounted a casting 2 which is also surmounted by a casting 3. Both of the castings are hollow and are.

provided with openings- 4 and 5 at. the front. end of the same. The hottolu part of tho lnclnher It has an opening which is provided with inwardly projecting lugs ti that al'e adapted to support a hurncr T. This lnn'ner may heot any desired type. (his or other lluid fuel is supplied h\ means of a pipe 5 to the said hurner. 'this pipe 8 enters the furnace through the opening 4 and outside is in communication with a valved hipe 9 which communicates with the source of fuel. The opening 5 is closed hy a door which may readily he removed so as to permit access to the comhust ion chalnher formed within the member 3%.

.\louutcd upon the casting It is a member it) round in shape which is formed of cast metal. The lnclnher I" has a tongue and groove connection, as indicated at ll, with the lnclnher It, so as to he readily removed from the same when it is desired to disasqr eiatc the mrts for the purposeot' cleanin or repair. 'lhe lnclnher It) is formed as n iollow casting: with two parallel side walls. pturalityof o wnings :33 extend through the aide walls. which openings are hounded h walls so as to have no communication wit I the space 12 hetwccn the side walls. The space 12 is unincloscd at the top of the memher and is also uninclosed at. the hottoul of thoae portions hctwecn the openings .21 hottoui it)" con wct-t with the insidewull of the lnclnher lit and is prcfcrahly formed integral tlu-rcwith.

hollow circular lnclnher l-l ol' cast metal surrounds the mcmher I and is secured thereto. The lncluhcrs It) and lit may he scpat'atclvformed and secured together, or, if desired. they may he formed as a single caatiluz. 'lhe up u-r part of the walls of the lnclnher ltl are ralahcted to acconnnodatcthe lower ends-of telescopingtuhular memhcrs H and t5. the said tuhular mcmhers are of sheet metal and are held in place nith respect to the lnclnher It) hy frictional engagement with the side walls and lower part of therahlu-tcd portions as hetorc mentioned. .\t the upper end of these tuhular mcmhcu: is a l'uemla-r lti \\hiclt i of cast g. clot. The said mcmhcr It; is formed with parallel side walls which provide a hollow spat-c I7 therehctwccn, which is closed at the top and open at the hottom. 'llund portions of these walls are ruhhct l in a manner similar to the walls of the member H) and the upper ends ill) of the tubular members it and there adapt ed to engage with the side and bottom of the rahheted port ions of the member tti.

The members It), H, 15 and It; are held together by means of brace rods 18 which are formed with heads at one end and screw threaded portions at their opposite ends which are adapted to engage with nuts. 'lhese rods extend through openings formed in llatwes l6 and I0 which are formed upon the members 16 and It), with which flanges the bolt heads and nuts engage. There are a number of these rods extending around the members 10 and In, so that. the members are secau-ely held in relative position.

In plan, the member 16 is shown in Fig. 2 and it is seen that the said member is formed with a series of projecting portions I!) which are hollow and the interiors of which are in communication with the space 17. These projections are formed as Integral )ttllS of the outer wall of the member Hi. 'l to lower portions of the members 19 are formed with o enings'which communicate with pipes 20, w tieh pipes likewise communicate with the interior of the members t3, as shown in Fig.

shield.

4. One portion of the member I3 is formed with a flanged o iening 2| which is in.eo|n|nunicaticn with a lne pipe 22, which pipe leads to the chimney for conduct ing away products of combustion.

As before stated, the member It! is formed with a series of openings 2.! which openings extend through the walls inclosing the space 12. These openings are for the puruse of admittim' air into the space iitcloscd y the inner wall of the member 10 and the member 14.

A sheet metal shield 24 surrounds and incloses the hollow members, pipes, etc. It is supported upon a llange which projects outwardly fmm the hollow member 13 and extends to a height substantially equal with the top of the heating device. hheet metal members 25 formed in a Z-shape with the middle part greatl lengthened are secured as by riveting to t to outer tubular member 15, the outer edges of these members bear against the inner Sltlt'tlfglltt shicld'Q-t. The said members are of the same height as the lly virtue of the fact that these members 25 are secured to the member 15 they become highly heated by the radiated heat and the air in hissing around them ahsoi'bs considerable iept from them. They, also serve as stlll'enmg members to brace the outer shield.

A casing 26 is mounted upon the base member I and int-loses the members .2 and 3 amt the heating device which is mounted upon the member .i. The front part of this casing is cut away so. as to accommodate the front portions of the members 2 and '8. At the upper end of the casing are pipes 27 which will conduct the heated air to the places that may be desired.

it will be noted that the products of comhustion from the burner are caused to lirst. travel through the s atee l. which in comprchemlcd hc-t ween I nc walls of the member It) and between the tubular members It and i5. 'l'hcy will then enter the space I? in the member It. and passing ut through the hollow projections It! formed upon the member 16 will pass down through the pipes 2t) and enter the interior of the member l3. (irculating around this member, they will next pass through the line pi )t 22 and enter the chimnev, from whence t I('\' will pass to the atmosp iere. The cool air upon entering will mss through the openings 23 in the mem |cr It) and up through the central air shaft which is inclosed by the tubular member t-l. Additional air will likewise circulate around he exterior of the tubular Incluher I! and also around the tubular member .20, as well asarouud the flue pipe 22. .\ll the air entering the casing after being heated willpass to the u iper port on of the casing 26, where it will K conducted through the wipes 27.

Particular importance is attached to the fact that a column of air is caused to ascend through the central port on of the heater. In the ordinary types of heater the burner is placed in a position similar to the manner which I have shown and a central tubular member is arranged above thehurner to carry away the products of combustion. in

such a construction only a small portion of course which it is caused to assume, sullicicnt time is given the air passing through the casing to extract all the heat units which we contained within the products of combustion, and so to obtain the highest. elliciency from the device, whichof couise chcapcns its tmcration.

The whole heater is simple in construct ion and may readily be disassemhlml for purposes of repair and cleaning;
